N-[2-(oxetan-3-oxycarbonyl)]phenylsulfonyl-N'-(4,6-dimethoxypyrimidin-2-yl)urea.

The compounds of the formula I can be prepared by either

a) reacting a phenylsulfonamide of the formula II ##STR6## in which R₂ and X are as defined under formula I, with an pyrimidinyl-, triazolyl- or triazinylcarbamate or -thiocarbamate of the formula III ##STR7## in which W, Z and R₁ are as defined under formula I and R₁₅ is phenyl or substituted phenyl, in the presence of a base, or

b) reacting a sulfonylcarbamate or -thiocarbamate of the formula IV ##STR8## in which R₂, W, X and Z are as defined under formula I and R₁₅ is as defined under formula III, with an amine of the formula V

    H.sub.2 N--Z                                               (V)

in which Z is as defined under formula I, in the presence of a base, or

c) reacting a phenylsulfonamide of the formula II ##STR9## in which R₂ and X are as defined under formula I, with an pyrimidinyl-, triazolyl- or triazinyl isocyanate or isothiocyanate of the formula VII

    Y═N═C--Z                                           (VII)

in which Z is as defined under formula I and Y is oxygen or sulfur, in the presence of a base.

Compounds of the formula I can also be prepared by reacting a compound of the formula VIII with a compound of the formula V in the presence of an ammonium-, phosphonium-, sulfonium- or alkali metal cyanate salt of the formula X

    M.sup.+ OCN.sup.-                                          (X)

wherein M is an alkali metal or the group R₁₅ R₁₆ R₁₇ R₁₈ Q, in which R₁₅ R₁₆ R₁₇ R₁₈ independently from another is C₁ -C₈ -alkyl, benzyl oder phenyl, with the total number of C-atoms not greater than 36; and Q is nitrogen, sulfur or phosphorus. According to this method the compounds N-[2-(oxetan-3-oxycarbonyl)]phenylsulfonyl-N'-(4-methoxy-6-methyl- 1,3,5-triazinyl)-urea;

N-[2-(oxetan-3-oxycarbonyl)]phenylsulfonyl-N'-(4,6-dimethylpyrimidin-2-yl)urea;

N-[2-(oxetan-3-oxycarbonyl)]phenylsulfonyl-N'-(4-methoxy-6-methypyrimidin.2-y)urea; and

N-[2-(oxetan-3-oxycarbonyl)]phenylsulfonyl-N'-(4,6-dimethoxypyrimidin-2-yl)urea can be prepared with advantage. Such reactions are described in Swiss Patent No. 662 348.

The reactions to give compounds of the formula I are advantageously carded out in aprotic, inert organic solvents. Such solvents are hydrocarbons, such as benzene, toluene, xylene or cyclohexane, chlorinated hydrocarbons, such as methylene chloride, chloroform, carbon tetrachloride or chlorobenzene, ethers, such as diethyl ether, ethylene glycol dimethyl ether, diethylene glycol dimethyl ether, tetrahydrofuran or dioxane, nitriles, such as acetonitrile or propionitrile, and amides, such as dimethylformamide, diethylformamide or N-methylpyrrolidone. The reaction temperatures are preferably between -20° and +120° C.

The reactions in general proceed slightly exothermically and can be carded out at room temperature. The mixture is advantageously heated to the boiling point of the reaction mixture for a short time for the purpose of shortening the reaction time or to start the reaction. The reaction times can also be shortened by addition of a few drops of base as a reaction catalyst. Suitable bases are, in particular, tertiary amines, such as trimethylamine, triethylamine, quinuclidine, 1,4-diazabicyclo[2.2.2]octane, 1,5-diazabicyclo[4.3.0]non-5-ene or 1,5-diazabicyclo[5.4.0]undec-7-ene. However, inorganic bases such as hydrides, such as sodium hydride or calcium hydride, hydroxides, such as sodium hydroxide and potassium hydroxide, carbonates, such as sodium carbonate and potassium carbonate, or bicarbonates, such as potassium bicarbonate and sodium bicarbonate, can also be used as bases.

The end products of the formula I can be isolated by concentrating the mixture and/or evaporating off the solvent and purified by recrystallisation or trituration of the solid residue in solvents in which they are not readily soluble, such as ethers, aromatic hydrocarbons or chlorinated hydrocarbons.

In the preparation processes described above for compounds of the formula I, R₁₅ is preferably phenyl which can be substituted by C₁ -C₄ alkyl or halogen, especially preferably phenyl.

The phenylsulfonamides of the formula II are novel compounds which have been developed and prepared specifically for the preparation of the active ingredients of the formula I. The present invention thus also relates to them. They can be prepared from the corresponding phenylsulfonyl chlorides of the formula VIII ##STR10## in which R₂ and X are as defined under formula I, by reaction with ammonia. Such reactions are known and familiar to the expert.

The phenylsulfonyl chlorides of the formula VIII are novel compounds which have been developed and prepared specifically for the preparation of the active ingredients of the formula I. The present invention therefore likewise relates to them. The phenylsulfonyl chlorides of the formula Vffl are prepared by reacting the correspondingly substituted 2-chlorosulfonyl-benzoyl chlorides (cf., for example, D. Davis, Soc. 2042, 2044 (1932)) with a compound of the formula IX ##STR11## in which X is as defined under formula I, in the presence of a base. Such reactions are known and familiar to the expert.

Phenylsulfonyl chlorides of the formula VIII in which X is oxygen can also be prepared by reacting 2-isopropyhhiobenzoic acid (cf., for example, H. Gilman, F. J. Webb, Am. Soc. 71, 4062-4063) with thionyl chloride to give the corresponding benzoyl chloride, which is then converted into the corresponding oxetan-3-yl 2-isopropylthiobenzoate with 3-hydroxyoxetane in the presence of a base, to give finally the sulfonylchloride of the formula VIII by reaction with chlorine. Such reactions are known and familiar to the expert.

Compounds of the formula IX and their preparation are known (cf., for example, B. Lamm et. al., Acta Chem. Scand. 28, 701 (1974) or J. Org. Chem. 48, 2953-2956 (1983)).

The sulfonylcarbamates and -thiocarbamates of the formula IV are novel and the present invention relates to them. They can be obtained, for example, by reaction of the sulfonamides of the formula II with diphenyl carbamate or thiocarbamate in the presence of a base. Such reactions are known and familiar to the expert.

The amines of the formula V are described in European Patent Applications 0 007 687, 0 030 138, 0 073 562 and 0 126 711, and in U.S. Pat. No. 4,579,584.

Processes for the preparation of N-pyrimidinyl- and N-triazinylcarbamates are described, for example, in EP-A-0 101 670. N-Triazolylcarbamates can be prepared analogously.

The active ingredients of the formula I are as a rule employed successfully at rates of application of 0.001 to 2 kg/ha, in particular 0.005 to 1 kg/ha. The doses required for the desired action can be determined by experiments. It depends on the nature of the action, the development stage of the crop plant and of the weed and on the application conditions (location, time, method) and can, as a result of these parameters, be varied within wide ranges.

The compounds of the formula I are distinguished by growth-inhibiting and herbicidal properties which render them excellent for use in crops of useful plants, in particular in cereals, cotton, soya, rape, maize and flee, use in soya crops and cereals being especially preferred. Control of the weeds in soya crops is preferably postemergence. The compounds of the formula I are distinguished in particular by their good degradability.

The invention also relates to herbicidal and plant growth-regulating compositions which comprise a novel active ingredient of the formula I, and methods for inhibition of plant growth.

Plant growth regulators are substances which cause agronomically desirable biochemical and/or physiological and/or morphological changes in/on the plants.

The active ingredients present in the compositions according to the invention influence plant growth in various ways depending on the time of application, dosage, mode of application and environmental conditions. Plant growth regulators of the formula I can, for example, inhibit the vegetative growth of plants. This type of action is of interest on lawn areas, in the growing of ornamentals, in fruit plantations, on road embankments and on sports fields and industrial premises, and also for controlled inhibition of secondary shoots, such as on tobacco. In agriculture, inhibition of the vegetative growth of cereals leads to reduced lodging via strengthening of the stem, and similar agronomic actions are achieved in rape, sunflowers, maize and other crop plants. The number of plants per unit area can moreover be increased by inhibition of the vegetative growth. Another field of use of growth inhibitors is selective control of ground-covering plants in plantations or wide-row crops by severe inhibition of growth, without killing these ground-covering plants, so that competition against the main crop is excluded, but the agronomically positive effects, such as prevention of erosion, nitrogen bonding and loosening of the soil, are retained.

A method for inhibition of plant growth is to be understood as meaning control of the natural plant development without changing, in the sense of mutation, the life-cycle of the plants determined by genetic properties. The method of growth regulation is used at a point in time of the development of the plants which is to be determined in the individual case. The active ingredients of the formula I can be applied before or after emergence of the plants, for example even to the seeds or the seedlings, to roots, tubors, stems, leaves, flowers or other plant pans. This can be effected, for example, by applying the active ingredient itself or in the form of a composition to the plants and/or by treatment of the nutrient medium of the plants (soil).

Various methods and techniques are suitable for use of the compounds of the formula I or compositions containing them for regulating plant growth, for example the following:

i) Seed dressing

a) Dressing the seeds with an active ingredient formulated as a wettable powder by shaking in a vessel until the active ingredient is distributed uniformly over the seed surface (dry dressing). Up to 4 g of active ingredient of the formula I (in the case of a 50% formulation: up to 8.0 g of wettable powder) are used here per kg of seed.

b) Dressing of the seeds with an emulsion concentrate of the active ingredient or with an aqueous solution of the active ingredient of the formula I formulated as a wettable powder by method a) (wet dressing).

c) Dressing by dipping the seed in a mixture containing up to 1000 ppm of active ingredient of the formula I for 1 to 72 hours and if appropriate subsequent drying of the seed (seed soaking).

Dressing of the seed and treatment of the germinated seedling are of course the preferred methods of application, because the treatment with the active ingredient is directed completely toward the target crop. As a rule 0.001 g to 4.0 g of active substance are used per kg of seed, it being possible to deviate upwards or downwards from the limit concentrations stated (repeat dressing) depending on the method, which also allows the addition of other active ingredients or micronutrients.

ii) Controlled release of the active ingredient

The active ingredient is absorbed in solution onto mineral granule carriers or polymerised granules (urea/formaldehyde) and allowed to dry. If appropriate, a coating which allows the active ingredient to be released in metered form over a certain period of time can be applied (coated granules).

The compounds of the formula I are employed in unchanged form, as obtainable from the synthesis, or preferably with the auxiliaries customary in formulation technology, and are therefore processed, for example, to emulsifiable concentrates, directly sprayable or dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granules and also capsules in, for example, polymeric substances in a known manner. The methods of use, such as spraying, misting, dusting, wetting, sprinkling or pouring, are, like the nature of the compositions, chosen according to the effects required and the given circumstances.

The formulations, i.e. the compositions, formulations or preparations comprising the active ingredient of the formula I and if appropriate one or more solid or liquid additives, are prepared in a known manner, for example by intimate mixing and/or grinding of the active ingredients with extenders, for example with solvents, solid carriers and if appropriate surface-active ingredients (surfactants).

Possible solvents are: aromatic hydrocarbons, in particular the fractions C₈ to C₁₂, such as mixtures of alkylbenzenes, for example xylene mixtures, or alkylated naphthalenes; aliphatic and cycloaliphatic hydrocarbons, such as paraffins, cyclohexane or tetrahydronaphthalene; alcohols, such as ethanol, propanol or butanol; glycols and ethers and esters thereof, such as propylene glycol or dipropylene glycol ether; ketones, such as cyclohexanone, isophorone or diacetone alcohol; strong polar solvents, such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or water; vegetable oils and esters thereof, such as rape, castor or soya oil; and if appropriate also silicone oils.

Solid carriers which are used, for example for dusts and dispersible powders, are as a rule natural rock powders, such as calcite, talc, kaolin, montmorillonite or attapulgite. Highly disperse silicic acid or highly disperse absorbent polymers can also be added to improve the physical properties. Granular, adsorbent granule carriers are porous types, for example pumice, crushed brick, sepiolite or bentonitc, and non-sorbent cartier materials are, for example, calcite or sand. A wide range of pregranulated materials of inorganic or organic nature, such as, in particular, dolomite or comminuted plant residues, can moreover be used.

Surface-active ingredients are nonionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient of the formula I to be formulated. Surfactants is also to be understood as meaning surfactant mixtures.

Suitable artionic surfactants can be either so-called water-soluble soaps or water-soluble synthetic surface-active ingredients.

Soaps are the alkali metal, alkaline earth metal or substituted or unsubstituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), for example the sodium or potassium salts of oleic or stearic acid, or of naturally occurring fatty acid mixtures, which can be obtained, for example, from coconut oil or tallow oil. The fatty acid methyltaufine salts may furthermore also be mentioned.

More often, however, so-called synthetic surfactants are used, in particular fatty alcohol sulfonates, fatty alcohol sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.

The fatty alcohol sulfonates or sulfates are as a rule in the form of alkali metal, alkaline earth metal or substituted or unsubstituted ammonium salts and contain an alkyl radical having 8 to 22 C atoms, alkyl also including the alkyl moiety of acyl radicals, for example the sodium or calcium salt of ligninsulfonic acid, of dodecylsulfate or of a fatty alcohol sulfate mixture prepared from naturally occurring fatty acids. These also include the salts of sulfuric acid esters and sulfonic acids of fatty alcohol-ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and a fatty acid radical having 8-22 C atoms. Alkylarylsulfonates are, for example, the Na, Ca or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid or a naphthalenesulfonic acid-formaldehyde condensation product.

Corresponding phosphates, for example salts of the phosphoric acid ester of a p-nonylphenol-(4-14)-ethylene oxide adduct, or phospholipids are furthermore also suitable.

Nonionic surfactants are in particular polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the aLkyl radical of the alkylphenols.

Other suitable nonionic surfactants are the water-soluble polyethylene oxide adducts, containing 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups, with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain. The compounds mentioned usually contain 1 to 5 ethylene glycol units per propylene glycol unit.

Examples of nonionic surfactants are nonylphenol polyethoxyethanols, castor oil polyglycol ether, polypropylene-polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.

Fatty acid esters of polyoxyethylenesorbitan, such as polyoxyethylenesorbitan trioleate, are furthermore also suitable.

The cationic surfactants are in particular quatemary ammonium salts which contain at least one alkyl radical having 8 to 22 C atoms as the N-substituent and lower halogenated or unhalogenated alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

The surfactants customary in formulation technology are described, inter alia, in the following publications:

"McCutcheon's Detergents and Emulsifiers Annual", Mc Publishing Corp., Glen Rock, N.J.1988.

M. and J. Ash, "Encyclopedia of Surfactants", Vol.I-III, Chemical Publishing Co., New York, 1980-1981.

Dr. Helmut Stache "Tensid-Taschenbuch" (Surfactant Handbook), Carler Hanser Verlag, Munich/Vienna 1981.

The pesticidal compositions as a rule comprise 0.1 to 99%, in particular 0.1 to 95%, of active ingredient of the formula I, 1 to 99% of a solid or liquid additive and 0 to 25%, in particular 0.1 to 25%, of a surfactant.

While concentrated compositions are more preferable as commercial goods, the end user as a rule uses dilute compositions.

Preparation examples:

Example H1:

2-(Thiaetan-3-oxyCarbonyl)phenylsulfonyl chloride: ##STR12## A solution of 52.8 g of 2-chlorosulfonylbenzoyl chloride and 100 ml of absolute toluene is added dropwise to a mixture of 20.7 g of 3-hydroxythiaetan, 20.0 g of pyridine and 250 ml of absolute toluene at a temperature of 0° to 10° C. The reaction mixture is then stirred at a temperature of 20°-25° C. for 2 hours and 300 ml of ice-water are subsequently added. A toluene solution of 2-thiaetanoxycarbonylphenylsulfonyl chloride is obtained by separating off the organic phase, washing it with water and drying it over sodium sulfate, and is employed in Example H2 without further working up.

Example H2:

2-(Thiaetan- 3-oxycarbonyl)phenylsulfonamide: ##STR13## 8.5 g of ammonia are passed into a toluene solution of 2-(thiaetan-3-oxycarbonyl)phenylsulfonyl chloride (preparation described in Example H1 ) in the course of 1 hour. After 400 ml of ice-water has been added to the reaction mixture, the mixture has been filtered and the product has been washed with water and then dried, 39.3 g of 2-thiaetanoxycarbonylphenylsulfonamide having a melting point of 145° to 146° C. are obtained.

Example H3:

N-[2-(Thiaetan-3-oxycarbonyl)phenylsulfonyll-N'-(4-chloro-6-methoxy- 1,3-pyrimidin-2-y 1)urea: ##STR14## A mixture of 0.69 g of diazabicyclo-[5.4.0]-undec-7-ene (1.5-5) and 5 ml of absolute dioxane is added dropwise to a mixture of 1.23 g of 2-(thiaetan-3-oxycarbonyl)phenylsulfonamide, 1.26 g of 4-chloro-6-methoxy-1,3-pyrimidin-2-yl phenylcarbamate and 20 ml of absolute dioxane and the mixture is then stirred at a temperature of 20° to 25° C. for 4 hours. Pouring the mixture into water, dropwise addition of 10% hydrochloric acid to pH 5, extraction with ethyl acetate, drying of the organic phase, evaporation and crystallisation from ethyl acetate gives 1.15 g of N-[2-(thiaetan-3-oxycarbonyl)phenylsulfonyl]-N'-(4-chloro-6-methoxy- 1,3-pyrimidin-2-yl)urea of melting point 180° to 181° (decomompositoin).

Example H4:

2-Isopropylthiobenzoyl chloride: ##STR15## A mixture of 15.7 g of 2-isopropylthiobenzoic acid and 15.7 g of thionyl chloride is heated to the reflux temperature very slowly and kept under reflux until the evolution of gas has ended. 17.3 g of non-purified 2-isopropylsulfonylbenzoyl chloride are obtained as a yellow oil by evaporating off all the excess thionyl chloride.

Example H5:

Oxetan-3-yl 2,iSopropylthiobenzoate: ##STR16## A mixture of 12.9 g of 2-isopropylthiobenzoyl chloride and 20 ml of absolute toluene is added dropwise to a mixture of 4.44 g of 3-hydroxyoxetane, 6.64 g of pyridine and 60 ml of absolute toluene at a temperature of 15° to 20° C. The suspension formed is stirred at a temperature of 20°-25° C. for 2 hours and at a temperature of 40°-45° C. for a further 3 hours. Adding water to the reaction mixture, washing the organic phase with water and drying and evaporating it gives 12.6 g of oxetan-3-yl 2-isopropylthiobenzoate as a pale yellow oil.

Example H6:

2-(Oxetan-3-oxycarbonyl)phenylsulfonyl chloride: ##STR17## 11.2 g of chlorine are passed into a mixture of 12.6 g of oxetan-3-yl 2-isopropylthiobenzoate, 12.9 g of sodium acetate and 100 ml of 50% acetic acid at a temperature of -5° to 0° C. in the course of 1 hour, and the mixture is then stirred at a temperature of 0° C. for 15 minutes. By adding methylene chloride to the reaction mixture, washing the organic phase with ice-water and drying it, a methylene chloride solution of 2-(oxetan-3-oxycarbonyl)-phenylsulfonyl chloride is obtained, which is employed in Example H7 without further purification.

Example H7:

2-(Oxetan- 3-oxycarbonyl)phenylsulfonamide: ##STR18## 2.5 g of ammonia are passed into a methylene chloride solution of 2-(oxetan-3-oxycarbonyl)phenylsulfonyl chloride (Example H6) at a temperature of 0° to 5° C. in the course of 45 minutes. By adding water to the reaction mixture, washing the organic phase with water, drying and evaporating it and crystallising the residue from a methylene chloride/diethyl ether mixture, 6.7 g of 2-(oxetan-3-oxycarbonyl)phenylsulfonamide of melting point 169° to 170° C. are obtained.

Example B1: Herbicidal action before emergence of the plants

Plastic pots are filled with expanded vermiculite (density: 0.135 g/cm³, water adsorption capacity: 0.565 l/l). After saturation of the non-adsorbent vermiculite with an aqueous active ingredient emulsion in deionised water which contains the active ingredients in a concentration of 70.8 ppm, seeds of the following plants are sown on the surface: Nasturtium officinalis, Agrostis tenuis, Stellaria media and Digitaria sanguinalis. The test vessels are then kept in a climatically controlled chamber at a temperature of 20° C., an illumination of about 20 klux and a relative atmospheric humidity of 70%. During a germination phase of 4 to 5 days, the pots are covered with transparent material, to increase the local atmospheric humidity, and watered with deionised water. After the 5th day, 0.5% of a commercially available liquid fertiliser is added to the watering water. The test is evaluated 12 days after sowing and the action on the test plants is rated according to the following scale:

Example B2: Postemergence herbicidal action (contact herbicide)

After emergence (in the 4--to 6-leaf stage), a number of weed plant, both monocotyledonous and dicotyledonous, were sprayed with an aqueous active ingredient dispersion in a dosage of 8-500 g of active substance per hectare, and these were kept at 24°-26° C. and 45-60% relative atmospheric humidity. The test is evaluated 15 days after the treatment.

After 3 weeks, the herbicidal action is rated with a nine-level (1=complete destruction, 9=no action) rating scale in comparison with an untreated control group. Ratings of 1 to 4(in particular 1 to 3) indicate a good to very good herbicidal action. Ratings of 6 to 9 (in particular 7 to 9) indicate a good tolerance (in particular by crop plants).

The compounds of the formula I show a potent herbicidal action in this test.

Example B3: Herbicidal action for paddy rice The aquatic weeds Echinochloa crus galli and Monocharia vag. are sown in plastic beakers (60 cm² surface area, 500 ml volume). After sowing, the beakers are filled with water to the soil surface. 3 days after sowing, the water level is increased to slightly above the soil surface (3-5 mm). The application is carried out 3 days after sowing by spraying the test substances onto the vessels. The dose used corresponds to an amount of active ingredient of 8-500 g of active substance per hectare. The plant beakers are then placed in a greenhouse under optimum growing conditions for the rice weeds, i.e. at 25°-30° C. and high atmospheric humidity.

The tests are evaluated 3 weeks after the application. The compounds of the formula I damage the weeds in this test.
